Dynamic Mechanical Analysis and Thermo-Gravimetric Analysis on Chopped Strand Mat Reinforced with Polyester Resin and Graphite Powder
Fiber reinforced plastics have been widely used for manufacturing aircrafts and spacecrafts structural parts because of their high mechanical, physical properties. These are used in manufacturing of structural composites, printed circuit boards and in a wide range of special-purpose products which are included in medical field as well. Within reinforcing materials chopped strand mats are the most frequently used in structural constructions because of their properties such as viscoelasticity, strength and high thermal stability. The present work focuses on mechanical and thermal properties of chopped strand mat reinforced with polyester resin and filler as graphite powder (which has high melting point) in different weight fractions. Evaluation of material properties is tested using Thermo-Gravimetric Analysis and Dynamic Mechanical analysis at a standard temperature ranging between 20°C - 460°C and evaluated. The results show that inclusion of graphite powder in chopped strand mat exhibit better enhancement in results when compared.
